Great summary Heidi.... is crazy and anoying at first how long some of them take to validate, like Kraken or Coinbase. But at the end I hope those also have more "legal backup" and less likely to shot down, that is what we hope at least. I would add that anybody that has a Coinbase account can also use Gdax, is the same backend web, more gear for daytrader, and the fees are way cheaper. You can move your funds instantly between them, is really nice, and you safe a BUNCH of money
